FABRCKTURFING IMPLEIVI ENT.

SPECIFICATION forming part of Letters Patent No. 377,192, dated January 31, 1888.

To all whom it may concern:

Be it known that I, ELM E. Connnrna citi- Zen of the United States, residing at Peoria, in the county of Peoria and State of Illinois, have invented certain new and useful Improvements in Fabric-Turting Implements; and I do herebydeelare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to machines for turfing fabrics.

Heretofore machines of this kind as commonly constructed are capable of use only on fabrics with wide meshes, the only exception to this rule being machines which are too complicated and expensive to permitof extensive use.

The object of the present invention is to produce a turfing or embroi'dering machine which shall be simple and cheap in construction, not liable to get out of order, and which shall be capable of being used on close as well as loose woven fabrics, thus enabling the kind of work done by these machines to be performed on the finer grades of cloth.

Furthermore, the object of the invention is to produce a turfing-machinc having combined therewith a feeding device whereby a uniform movement of the device is automatically caused during the operation of turting or embroider-l ing, the said device being capable of adjustment to regulate the length of each advancing step.

Furthermore, the invention has for its object to produce an adjustable stop for regulating the length of the loops formed.

IVith these objects in view my invention consists in a turfing or embroidering machine comprising a reciprocating needle for carrying yarn or thread through the fabric to be worked upon, the said needle having an eye, through which the thread or yarn is passed, situated about midway of the exposed portion of the needle, and means operating in conjunction with the needle for retaining the yarn against being withdrawn from the fabric during the intervals between the stitches.

Furthermore, theinvention residesin a turfing or embroidering machine comprising a reciprocating needlebar, a needle attached to (No model.)

its lower end, and a sheath inclosing the nccdle-bar and provided with a spring having its end in contact with the needle, whereby the yarn is engaged during the upward movement of the needle and retained against withdrawal from the fabric during the interval between the stitches.

Furthermore, the invention resides in a turfing or embroidering machine comprising a needle-bar carrying a needle by which the thread or yarn is inserted into the cloth, an outer sheath, and a projection from the sheath engaging the bar, whereby the movement of the needle-bar is limited and regulated.

Furthermore, the invention resides in various details of construction novel in themselves, and which insure the effectiveness and accuracy of the device.

I have illustrated the invention in the accompanying drawings, in which- Figure lis a perspective view of the improved machine, the needle being represented at the limit of its downward movement. Fig. 2 is a central longitudinal vertical section of the machine, the section being taken on a line coincident with the direction of movement during operation. Fig. 3is aperspective view of the needle used. Fig. et is a perspective view of the adjustable stop whereby the length of the vibration of the needle is regulated. Fig. 5 is a perspective view of the device for securing the needles to the needle-bar, and Fig. 6 is a perspective view of the spring whereby the yarn or thread is retained between the stitches and a forward movement imparted to thek needle. Fig. 7 isan enlarged transverse section of the machine through the line w x, Fig. 2, the view being upward.

In the drawings, A represents the outer shell or sheath, by which the principal working parts of the device are inclosed or sustained. This shell or sheath is provided at its lower end with the curved depending projections A', which form what may be termed runners,77 serving to support the machine at the proper distance from the cloth upon which the work is to be done, and with an inward projection, c3.

In the use of my machine it is designed that the cloth upon which the cmbroidering is to be performed shall be held taut by thc aid of IOO a frame upon which it is stretched, or in any other suitable manner. f

B represents a shell of such size as to bereceived by the sheath A and capable of sliding up and down. therein. It is provided at its upper end with a handle, B'. This shell forms what may be termed a needle-bar, inasmuch l as the needle or needles by which theyarn or thread is passed through the cloth are carried by its lower end.

The means of securingthe needles in place is shown in Fig. 5 of the drawings. It consists, essentially, of the plate F,provided with the bent end f, which is passed through an opening in the lower end of shell B, and is thereby held in place. This end f is provided with one or more 'openings for the reception of needles.

The letter f* represents a transverse piece provided upon its underface with a`notch or 'notches of such size and shape to permit the passage of the needle.

,The face of the plate F above the cross-piece fet is formed with a series of grooves,whieh aid in retaining the needles in place after they have been inserted. The needles are held.

against dropping out by the springs f3, one of which is provided for each needle used. The vbent ends of the springs engage with grooves in the needles. The upper end of the plate is provided with a projection, f5,which holds the plate at an angle to the face of the needle-bar.

The plate F is capable of a slight vibratory motion, the axis of which movement is the point at which the plate is attached to needlebar. The distance which the plate F or needle-clamp Vibratesis regulated by the upturned oblique end c of the plate C, which end is always within the are described by the plate F in its vibration.

The preferred means of securing the plate to the needle-bar is by forming small projections b on the inner face of the shell B, which may be done by stamping during the process of making the samef These projections are provided with bent ends, which are designed to enter holes or indentations c', formed in the plate. That part of the plate C having the holes or indentations is of spring metal, so that the projections are retained firmly against displacement after being introduced -into the holes. By depressing the plate free from the projections it may be slid along at will to change its position,.and thereby change the length of the stitch.

The means whereby the thread or yarn is prevented from being withdrawn between stitches and the length of loop regulated will now be described.' j

D represents a leaf-spring lwhich is formed with or has attached to its lower end a series of sharp projections, d3. The upper portion of the spring is provided with the bent end D', which is designed to lie fiat with the ,outer face of the sheath A when the parts are in operative position. The spring is provided with the reduced necks d' and d2 and withthe lip d4. In attaching the spring .to the sheath the portion D is passed through the opening a .Y

pressing the end of the same down to bring the neck d flush with the teeth a.

The needle by which the thread or yarn is passed through the fabric is represented byl the letter E. It is provided at its upper end with a beveled portion, e', and with a groove, e. The upper portion of the lower part of the needle is hollow, and the upper and lower portions are in different vertical planes. The juncture betweenthe two parts is made by the inclined portion e5. The top of the hollow portion is providedwith a flaring mouth, e, in order to offer no obstruction to the free and smooth passage of the yarn.

The needle is provided with thelongitudinal slot e, extending from the eye c2 to the lower portion of the flaring portion et, so that the threading of the machine may be accomplished f rapidly by first passing the thread or yarn through the mouth, then through the eye, and, finally, by drawing the thread or yarnv taut and through the slot into the hollow portion of the needle. The lower portion, e6, of the needle is along point gradually tapering from a very sharp end to the eye, so that it may be easily inserted into cloth of the closest meshes.

In the operation of the machine the feet AL are placed upon the cloth upon which the work is to be done when the needle is at the limit of its upward movement. The needle-bar is forced down, forcing the needle carrying the thread or yarn-through the fabric.

comes in contact with the projection a3 from the inner face of the sheath A. This forces the needle to assume a vertical position, and, the needle-bar and needle acting as a lever and the fabric as a fulcrum, the machine is moved forward one step. When the needlevbar has reached its lowest point, it is drawn up, and as the eye of the needle passes the teeth on the spring D the yarn or thread is caught and held until another downward movement is made. The spring D being vertically adj ustable, the point at which the thread or yarn is caught, and consequently the length of the loops formed, may be regulated at will. The length of the stitch may beregulatedby adjusting the plate C to determine the vibration of the plate F.

Having thus described my invention,what I claim as new, and desireto secure'by Letters Patent, is-l As the Y bar descends the inclined facevof the plate Fv IOO IIO

attached to the needle-bar, substantially as described. Y

3. The combination, in a turting-inacliine, of the needle having the upper beveled end, the groove, and the hollow portion, and the retaining device consisting ot' the plate F, the

spring-fingers attached to the plate, the npturned end provided with holes, and the crosspiece provided with the notches on its lower face.

4. The combination, with the shell Aand needle-bar B, of the needle-holder having its lower end pivot-ally connected with the needlebar, the needle set in said holder, the adj nstable spring C, having the end 0, which limits the oscillation ot' the free end of the needleholder, and the adjustable spring D, having` the serrated end d, irnpinging upon the needle and adapted to catch and arrest the yarn as the eye of the needle passes it, substantially as and for the purpose set forth.

In testimony whereof I affix my signature in presence ot' two witnesses.
